    pub backoff: Backoff,

Implementations

impl RetryPolicy

pub const fn exponential( initial: Duration, max: Duration, max_attempts: u32, ) -> Self

max_attempts attempts, waiting initial after the first failure and doubling, up to max.

pub const fn custom(delay: fn(u32) -> Duration, max_attempts: u32) -> Self

max_attempts attempts, waiting what delay says after each failure, given how many attempts have failed.

pub fn delay(&self, attempts: u32) -> Option<Duration>

The delay before the next attempt, after attempts attempts have failed; None when there are to be no more.
